Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments.
As shown in FIG. 1, the posture correction device of the present invention is entirely made of an elastic body 1 of the telescopic relative to the width W ₁ of the right and left end portions in the free state grain width dimension W ₀ of the left and right central region 2 A closed annular band portion 3 having a constricted shape and a connecting portion 4 for connecting the band portion 3 in the left and right central region 2 are integrally formed. As shown in FIG. 6, the posture correcting tool of the present invention is worn in the extended state with the band portion 3 hung on the shoulders from the back side of the user (from the top of the clothes), and the band portion 3 maintains the extended state. However, it can be rephrased as a posture holder that is configured to draw the user's scapula toward the center by the resilient forces F ₁ and F ₂ and keeps the posture of the user properly.
The elastic body 1 is, for example, a thermoplastic rubber (TPR) or a thermoplastic elastomer (TPE), and the hardness measured using a TYPE A tester defined in JIS K7312 is set to A2 to A12. Yes. Preferably, the hardness is A3 to A9. That is, the elastic body 1 is very soft like a jelly confectionery, and the closed annular band portion 3 is formed so as to be easily stretched by being elastically deformed with a small force.

As shown in FIGS. 2 and 3, the band part 3 has a flat part 6 near the left and right central region 2, and the flat part 6 is formed in an elliptical shape in cross section (see FIG. 4).
In the wearing state shown in FIG. 6, the band portion 3 is inevitably twisted, but the flat portion 6 is configured to abut along the back, and the flat portion 6 is used with a gently curved curved surface. Since it abuts on the back side of the person, the contact surface pressure is small and it feels as if it is weakly touched, and the uncomfortable feeling at the time of wearing is reduced. Moreover, since the flat part 6 contacts in a wide area, the frictional force with respect to clothes improves and it becomes difficult to produce a slip. Therefore, even if worn for a long time, even if the user walks or plays sports such as golf while wearing the posture correction tool of the present invention, without misalignment, and The elastic force F ₁ or F ₂ is applied so that the user can wear it without any sense of incongruity and keep the user in the correct posture.

Moreover, the band part 3 has the curved parts 7 and 7 in both right and left end parts, and the curved part 7 is formed in a cross-sectional polygonal shape (see FIG. 5). In addition, the cross section of the curved part 7 may be circular.
The bent portions 7 and 7 absorb the twist that is inevitably generated in the band portion 3 at the time of wearing, and even if the bent portions 7 and 7 having a polygonal circular cross section are twisted, the feeling of contact with the shoulder is small. Even if you use it for a long time, you will not feel pain in the shoulder.

As shown in FIG. 1, the connecting portion 4 has two bridges 8 and 8 arranged in a C shape.
The bridges 8 and 8 have a circular cross section or a polygonal shape (not shown) and are integrally connected to the band portion 3. A trapezoidal window 9 is formed inside the C-shaped bridges 8 and 8. The window portion 9 may be penetrating, or may be non-penetrating by leaving a thin film. A pair of left and right lever-type window portions 5 and 5 are formed outside the two bridges 8 and 8 (connection portion 4).

When the user's scapula is pulled toward the center of the back surface, a friction coefficient is applied to the surface of the band unit 3 so that the band unit 3 does not slip with respect to the user's clothes.
In the mounted state, the band portion 3 is in contact with the clothes worn by the user and slips on the clothes due to the surface friction of the elastic body 1 such as thermoplastic rubber (TPR) or thermoplastic elastomer (TPE). Does not occur. The user's clothes are preferably underwear or a functional inner that is in close contact with the body.

The use method (action) of the posture correction tool of the present invention described above will be described.
The posture correction tool of the present invention pulls the left and right end portions of the band portion 3 outward to be in an extended state, returns the wrist while moving it from the top of the head and moves it to the back side, and greatly expands the left and right (lion type) Through both the arms through the windows 5 and 5, the central region 2 is applied to the lower scapula so as to correspond to the center of the back surface, and is mounted as shown in FIG.
The band part 3 pulls the user's scapula to the center with the elastic forces F ₁ and F ₂ to return from the extended state. At this time, in the central region 2, as shown in FIG. 7, the band portion 3 is extended to the left and right, the trapezoidal window portion 9 is expanded to the left and right, and the two bridges 8, 8 are elongated, and the bridge 8 , 8 generate elastic tensile forces T _C , T _C. That is, the elastic forces F ₁ and F ₁ are generated by the resultant force of the tensile forces T _A and T _A generated in the upper band portion 3 of the central region 2 and the tensile forces T _C and T _C of the bridges 8 and 8. and the tensile results at the bottom of the band portion 3 of the central region 2 force _T B, and _{T B,} the tensile force _T C of the bridge 8, 8, the resultant force of _{T C,} spring force _F 2, _{F 2} is generated Pull the scapula to the center of the back.

The band part 3 abuts on the garment in a sufficiently stretched state, and maintains the stretched state without slipping on the garment even after being worn. In the band portion 3, the flat portions 6 and 6 disposed closer to the central region 2 are well extended, and the flat portions 6 and 6 are maintained in an extended state by friction with clothes. Pull is demonstrated strongly. On the other hand, the band part 3 is subjected to shoulder curved portions 7 of the right and left end portions extending slightly state, per the user's shoulders in the right and left end portions (curved portions 7) Is weak and does not cause pain. That is, since the band portion 3 has a friction coefficient that does not cause slipping on the clothes on the surface, the band portion 3 extends between the flat portions 6 and 6 near the central region 2 and the bent portions 7 and 7 at the left and right end portions. The flat portions 6 and 6 are well stretched and are relatively locally pulled, and the bent portions 7 and 7 are kept relatively weakly pulled. Accordingly, the band portion 3 does not pull the user's shoulders backward (as in the prior art), but (in the posture correction tool of the present invention) along the direction of movement of the shoulder joint as indicated by the arrow R in the figure. Applying a tensile force, the user stretches his chest so that his line of sight rises, and the elastic forces F ₁ and F ₂ that pull the scapula to the center of the back surface are applied to ensure the user's back muscles. Stretch and maintain correct posture.

Next, the posture correction tool set of the present invention will be described.
As shown in FIG. 8, a set of posture correction tools H, M, and S that are formed of a stretchable elastic body 1, have the same shape in a free state, and have different hardness (hardness). Consists of.
Posture correction tools H, M, and S are classified into three types of hardness (hardness) : “hard”, “medium”, and “soft”, and the width dimension W ₀ of the left and right central region 2 is narrowed down in a free state ( A constricted annular band portion 3 having a constricted shape and a connecting portion 4 for connecting the band portion 3 in the left and right central region 2 are integrally formed. It has an oblong flat part 6 and has curved parts 7 and 7 having a polygonal cross section or a circular shape at both left and right ends. The connecting portion 4 has two bridges 8 and 8 arranged in a C-shape, a trapezoidal window portion 9 is formed inside the bridges 8 and 8, and outside the bridges 8 and 8. Are formed with a pair of left and right lever-shaped window portions 5 and 5.
The elastic body 1 is made of, for example, a thermoplastic rubber (TPR) or a thermoplastic elastomer (TPE). For the posture correction tools H, M, and S, the hardness measured using the TYPE A tester specified in JIS K7312 is set to A12 to A8 for “hard”, and set to A7 to A5 for “medium”. , “Soft” is set to A4 to A2. Preferably, “hard” is set as hardness A9, “medium” is set as hardness A6, and “soft” is set as hardness A3. Note that the posture correction tools H, M, and S are provided with a friction coefficient on the surface of the band portion 3 so that the clothes do not slip.

As shown in FIG. 9, each set of posture correction tools H, M, and S is configured so that the elastic forces F ₁ and F ₂ with respect to the extension of the elastic body 1 are different when the same person wears them. Yes.
As shown in FIG. 9A, the “hard” posture correction tool H applies elastic forces F ₁ and F ₂ that strongly pull the scapula to the center. That is, the posture correction tool H is worn when playing sports such as golf, tennis, baseball, soccer, or yoga, or is selected according to a physique such as a narrow shoulder width. The “medium” posture correction tool M has elastic forces F ₁ and F ₂ smaller than “hard” and is suitable for light exercise such as jogging and walking. The “soft” posture correction tool H applies elastic forces F ₁ and F ₂ that pull the scapula weakly toward the center. The “soft” posture correction tool H is suitable for being worn for a long time in daily life, and has an advantage that a feeling of tightening (constraint feeling) is weak and fatigue is difficult.

  The present invention can be modified in design. For example, the connecting portion 4 may have two bridges 8 and 8 intersecting in an X shape and the intermediate portions may be integrated with each other, or connected. The part 4 may have two or more bridges 8.

As described above, the posture correction tool according to the present invention is composed of the elastic body 1 that is stretchable as a whole, and is a closed annular band portion having a shape in which the width dimension W ₀ of the central region 2 in the left-right direction is narrowed in a free state. 3 and the connecting portion 4 for connecting the band portion 3 in the central region 2 are integrally formed, and in the mounted state, the band portion 3 is hung on both shoulders from the back side of the user and maintains the extended state. On the other hand, since the user's scapula is attracted to the center of the back surface with the elastic forces F ₁ and F ₂ , the elastic body 1 is soft and can be worn without feeling pain, Since it has a high degree of freedom and is hard to get tired, it can be used for a long time without any discomfort. The back posture of the user can be extended by the elastic forces F ₁ and F ₂ acting so as to pull the scapula, and the correct posture can be maintained.

Further, the band portion 3 has a flat portion 6 having an elliptical cross section near the left and right central region 2, and since the flat portion 6 abuts along the back in the mounted state, the flat portion 6 has a loose curve. Since it touches the user's back side with a heel-shaped curved surface, the contact surface pressure is small, and it feels as if it is weakly touched, and the uncomfortable feeling at the time of wearing can be reduced. Further, since the flat portion 6 is in contact with a wide area, the flat portion 6 is less likely to slip on the clothes, and even when worn for a long time, the flat portion 6 does not shift, and the elastic force F ₁ keeps the user in the correct posture. , F ₂ . Even if the user walks or plays a sport such as golf, the user can wear it without any misalignment.

  Further, since the band portion 3 has curved portions 7 and 7 having a polygonal cross section or a circular shape at both left and right end portions, the twist portion inevitably generated in the band portion 3 at the time of mounting can be absorbed. The feeling of hitting 7 and 7 on the shoulder is small, and it can be used for a long time without feeling pain in the shoulder.

Further, since the connecting portion 4 has two bridges 8 and 8 arranged in a C shape, the band portion 3 and the bridges 8 and 8 cooperate to bring the scapula to the back center. The pulling forces F ₁ and F _{2 that} are attracted are generated, so that the user's back can be surely extended and the correct posture can be maintained.

Further, when the user's scapula is pulled toward the center of the back surface, the band portion 3 gives a friction coefficient to the surface of the band portion 3 so that the user's clothes do not slip. 6 and 6 and the bent portions 7 and 7 at both the left and right end portions, the flat portions 6 and 6 are well stretched and locally pulled relatively strongly without being evenly stretched. The band part 3 keeps the state where the pull of the part is relatively weak, the band part 3 opens the user's shoulder so that the line of sight is raised, and the elastic force F ₁ and F ₂ that draws the scapula to the center of the back surface is applied. The user's back can be surely stretched and kept in the correct posture.

In addition, the posture correction tool set according to the present invention is formed of a stretchable elastic body 1, and is a set of posture correction tools having the same shape in a free state and different in hardness (hardness) of the elastic body 1. Each of the posture correction tools H, M, and S, which are composed of H, M, and S, is configured so that the elastic forces F ₁ and F ₂ with respect to the extension of the elastic body 1 are different when the same person wears them. Therefore, when a sport such as golf is used and a change in the usage situation in daily life, a desired one is selected from a set of posture correction tools H, M, and S, and the elasticity F ₁ , F ₂ (tightening force) can be adjusted. In addition, at the store, it is possible to select from a set of posture correction tools H, M, S and recommend the most desirable one to the customer.
